Music streaming service Tidal, launched in 2014 with the promise to provide artists with appropriate royalties for streaming, is facing a $5 million class-action lawsuit from Yesh Music and John Emanuele from the band the American Dollar alleging that Tidal streamed 116 of the band’s songs without paying back any royalty payments.

As Complex points out, Jay Z tweeted shortly after the official launch that Tidal planned to pay every artist, writer and producer featured on the service a 75% royalty rate, higher than anyone in the industry. The suit also claims that Tidal used faulty numbers to make payments to artists and undercut the money they owed to artists by an estimated 35%.
